The story so far: with the release of its Fifth Assessment Report, the Intergovernmental Panel on Climate Change has proved beyond reasonable doubt that it cannot be taken seriously.

Here are a few reasons why: IPCC lead author Dr Richard Lindzen has accused it of having “sunk to a level of hilarious incoherence.”[2] Nigel Lawson has called it “not science but mumbo jumbo”.[3] The Global Warming Policy Foundation’s Dr David Whitehouse[4] has described the IPCC’s panel as “evasive and inaccurate” in the way it tried dodge the key issue of the 15-year (at least) pause in global warming; Donna Laframboise[5] notes that is either riddled with errors or horribly politically manipulated – or both; Paul Matthews has found a very silly graph[6]; Steve McIntyre [7]has exposed how the IPCC appears deliberately to have tried to obfuscate the unhelpful discrepancy between its models and the real world data; and at Bishop Hill[8] the excellent Katabasis has unearthed another gem: that, in jarring contrast to the alarmist message being put out at IPCC press conferences and in the Summary For Policymakers, the body of the report tells a different story – that almost all the scary scenarios we’ve been warned about this last two decades (from permafrost melt to ice sheet collapse) are now been graded by scientists somewhere between “low confidence” to “exceptionally unlikely;” and this latest from the Mighty Booker.[9]

And there’s plenty more where that came from.

Now, of course, I fully appreciate how the climate alarmists are going to respond to these criticisms: same way they always do – with a barrage of lies, ad homs, cover-ups, rank-closings, blustering threats, straw men, and delusion-bubble conferences like the one they’ve just staged at the Royal Society in which one warmist pseudo-scientist after another mounts the podium to reassure his amen corner that everything’s going just fine and that those evil denialists couldn’t be more wrong.
